In CSS, floating is a method of taking an element out of the document flow. It will move the element to the left or right according to the value of float, and the elements around it will also be rearranged until its outer edge. until it hits the border of the containing box or another floated box.
The operating environment of this tutorial: Windows 7 system, CSS3&&HTML5 version, Dell G3 computer.
Floating is a method of taking an element out of the document flow, moving it to the left or right and rearranging elements around it.
The meaning of floating: The element with the floating attribute set will break away from the control of the ordinary standard flow and move to the position specified in its parent element. If the block-level element is placed on a line, the floating will break away from the standard flow. It does not occupy a position and will affect the standard flow. Floating can only float left and right, not up and down.
Floating is a very useful layout method that can change the order in which objects on the page flow forward and backward. The advantage of this is that it makes the layout of the content simple and has good scalability.
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<style>
img
{
float:right;
}
</style>
</head>
<body>
<p>在下面的段落中，我们添加了一个 <b>float:right</b> 的图片。导致图片将会浮动在段落的右边。</p>

Element floating characteristics:
1. Floating elements break away from the standard document flow and get rid of the restrictions of block-level elements and inline elements.
2. Floating elements have the effect of sticking to each other. When the width is not enough, an error message will appear. Automatic line wrapping
3. Although floating elements are separated from the standard document flow, they are not separated from the text flow, and will appear to be surrounded by words
Consequences caused by floating:
(1) Since the floating element is out of the document flow, the height of the parent element cannot be expanded, which affects elements at the same level as the parent element
(2) At the same level as the floating element The non-floating elements will follow, because the floating elements leave the document flow and do not occupy their original positions
(3) If the floating element is not the first floating element, the elements before it also need to be floated. Otherwise, it will easily affect the structural display of the page
, so the floats need to be cleared. So how to clear float? Recommended reading "How to clear floating in CSS? Introduction to 3 methods》

The Benefits of React: Performance, Reusability, and MoreApr 15, 2025 am 12:05 AMReact’s popularity includes its performance optimization, component reuse and a rich ecosystem. 1. Performance optimization achieves efficient updates through virtual DOM and diffing mechanisms. 2. Component Reuse Reduces duplicate code by reusable components. 3. Rich ecosystem and one-way data flow enhance the development experience.
React: Creating Dynamic and Interactive User InterfacesApr 14, 2025 am 12:08 AMReact is the tool of choice for building dynamic and interactive user interfaces. 1) Componentization and JSX make UI splitting and reusing simple. 2) State management is implemented through the useState hook to trigger UI updates. 3) The event processing mechanism responds to user interaction and improves user experience.
React vs. Backend Frameworks: A ComparisonApr 13, 2025 am 12:06 AMReact is a front-end framework for building user interfaces; a back-end framework is used to build server-side applications. React provides componentized and efficient UI updates, and the backend framework provides a complete backend service solution. When choosing a technology stack, project requirements, team skills, and scalability should be considered.
HTML and React: The Relationship Between Markup and ComponentsApr 12, 2025 am 12:03 AMThe relationship between HTML and React is the core of front-end development, and they jointly build the user interface of modern web applications. 1) HTML defines the content structure and semantics, and React builds a dynamic interface through componentization. 2) React components use JSX syntax to embed HTML to achieve intelligent rendering. 3) Component life cycle manages HTML rendering and updates dynamically according to state and attributes. 4) Use components to optimize HTML structure and improve maintainability. 5) Performance optimization includes avoiding unnecessary rendering, using key attributes, and keeping the component single responsibility.
React and the Frontend: Building Interactive ExperiencesApr 11, 2025 am 12:02 AMReact is the preferred tool for building interactive front-end experiences. 1) React simplifies UI development through componentization and virtual DOM. 2) Components are divided into function components and class components. Function components are simpler and class components provide more life cycle methods. 3) The working principle of React relies on virtual DOM and reconciliation algorithm to improve performance. 4) State management uses useState or this.state, and life cycle methods such as componentDidMount are used for specific logic. 5) Basic usage includes creating components and managing state, and advanced usage involves custom hooks and performance optimization. 6) Common errors include improper status updates and performance issues, debugging skills include using ReactDevTools and Excellent
React and the Frontend Stack: The Tools and TechnologiesApr 10, 2025 am 09:34 AMReact is a JavaScript library for building user interfaces, with its core components and state management. 1) Simplify UI development through componentization and state management. 2) The working principle includes reconciliation and rendering, and optimization can be implemented through React.memo and useMemo. 3) The basic usage is to create and render components, and the advanced usage includes using Hooks and ContextAPI. 4) Common errors such as improper status update, you can use ReactDevTools to debug. 5) Performance optimization includes using React.memo, virtualization lists and CodeSplitting, and keeping code readable and maintainable is best practice.
React's Role in HTML: Enhancing User ExperienceApr 09, 2025 am 12:11 AMReact combines JSX and HTML to improve user experience. 1) JSX embeds HTML to make development more intuitive. 2) The virtual DOM mechanism optimizes performance and reduces DOM operations. 3) Component-based management UI to improve maintainability. 4) State management and event processing enhance interactivity.
React Components: Creating Reusable Elements in HTMLApr 08, 2025 pm 05:53 PMReact components can be defined by functions or classes, encapsulating UI logic and accepting input data through props. 1) Define components: Use functions or classes to return React elements. 2) Rendering component: React calls render method or executes function component. 3) Multiplexing components: pass data through props to build a complex UI. The lifecycle approach of components allows logic to be executed at different stages, improving development efficiency and code maintainability.
